Offshore platform moving equipment importance evaluation method and offshore platform moving equipment importance evaluation system

Abstract

The invention discloses an offshore platform moving equipment importance evaluation method and an offshore platform moving equipment importance evaluation system. The method comprises the following steps: S1, the importance evaluation indexes of equipment are established; S2, the scoring standard of each importance evaluation index is established; S3, multiple evaluators determine the initial weight value of each importance evaluation index and the optimal order relation of the importance evaluation indexes respectively using an AHP method, and thus, multiple initial weight values of each importance evaluation index and multiple optimal order relations of the importance evaluation indexes are obtained; S4, calculation is performed on the multiple initial weight values of each importance evaluation index and the multiple optimal order relations of the importance evaluation indexes by use of a fuzzy Borda sequence value method to get the Borda value of each importance evaluation index; S5, the group weight value of each importance evaluation index and the optimal order relation of the importance evaluation indexes are generated according to the Borda value of each importance evaluation index; and S6, the importance of the equipment is calculated according to the group weight value of each importance evaluation index and the optimal order relation of the importance evaluation indexes. The invention puts forward an equipment combination group evaluation method based on an AHP method, a fuzzy Borda sequence value method and a Monte Carlo simulation method. Quantification of the importance of offshore platform moving equipment is realized.

AI Technical Summary

Problems solved by technology

It will take a lot of manpower, material resources and maintenance resources to analyze the equipment subsystems or parts in detail one by one and formulate maintenance strategies, but according to the actual situation, this is not necessary

At the same time, due to the limited maintenance resources, it is impossible and unscientific to maintain the high performance and high indicators of all components, equipment or systems on the platform

By comprehensively considering the special industry background of offshore oil and gas production, the complex structure of dynamic equipment, and the RRCM maintenance decision-making needs of offshore platform dynamic equipment, the existing equipment importance evaluation and classification methods cannot meet the needs.
